The attachment shown in Fig. 0 is securedin place and adjusted in substantially the same manner as alreadydescribed. The ear 0 is dropped into the hole (I and the pin 0' engagedwith slot 1:, so that by moving the lever B the delivery end of thehemmer can be adjusted for the line of stitching. The attachment of theparts, with the construction shown in Fig. 7, is the same as alreadydescribed, except that owing to the tapering form of the pin 0, it isnot necessary to raise the lever in withdrawing one attachment an dinserting another in place thereof. The ear or projection 0 forms thepivot in each case on which the hemmer is swung to adjust its deliveryend, and this swinging of the hemin the hole d, and such end movementfor the arrangement shown in Figs. 6 and '7 is permitted by the slotf',which allows the lever B to be swung to carry the hemmer D sidewise.

\Vhat I claim as new, and desire to secure by Letters Patent, is"

1. The combination of plate A, having hole (I, the plate (3, providedwith ear 0, fitting in the hole (I to render said plate 0 detachable andadjustable, the lever B, pivoted to plate A and struck up or recessed tooverlap the plate C, means for connecting the lever B and plate (7,whereby said plate maybe adjusted, and means for securing the lever B inthe position to which it may be turned, substantially as described.

2. The combination of plate A, having hole (I and notched edge e, theplate 0, provided with ear 0, fitting in the hole (I, said plate beingalso provided with pin 0, and the lever B, pivoted to plate A and havingan opening, I), to receive the pin 0, whereby said lever is connectedwith the plate C, said lever being struck up or recessed to be swungover upon and overlap the plate 0, and provided with a tooth, e, toengage the notchedv edge e of the 1 plate A, whereby the lever is heldin the position to which it maybe turned, substantially as described.
